I want to add Pokemon Journeys to my jellyfin server, but jellyfin fucks up everything because it thinks it the regular Pokémon show from 1997 and imports metadata for that....
The usual fix from the Jellyfin docs would be to check you file naming conventions, and add the TVDB or TMDB show ID to the folder so that it scrapes it correctly, or use the Identify option like @Rudee mentioned to select a better match from the UI after import.
Both TVDB and TMDB consider Pokémon Journeys to be Season 23 of the original Pokémon show, the OMDB seems to list it as a standalone show though, so you could import and match it against that metadata.
There are other submitted Merge Requests to that gnome-session GitLab repository that are 3 years old and are still open. This is only a proposal, and doesn't actually mean it's happening.
If GNOME developers want to focus on expanding Wayland support instead of maintaining X11 support, surely that's their choice - they're mostly volunteers anyway, shouldn't they get to decide what they want to work on?
If other developers still want X11 support, they can branch these session targets and X11 support code off into a separate package and handle maintaining it.
Jellyfin wrongly identifies show and messes up metadata
